| 摘 要： | 测定了施加小麦秆糖、玉米秆糠后植烟土壤中细菌、霉菌、施线菌、解磷菌、解钾菌、硝化细菌和反硝化细菌７类菌群的分布及数量；应用生物统计分析法比较了施加不同秸秆对烤烟试验田土壤微生物结构和数量的影响。结果表明，施加７５００ｋｇ／ｈｍ＾２的小麦秆糠、９０００ｋｇ／ｈｍ＾２的玉米秆糠和１５０００ｋｇ／ｈｍ＾２的玉米秆糠都能显著或极显著地增加２０～４０ｃｍ耕作层中微生物的数据。

| Abstract: | The distribution and quantity of bacteria, fungi, actinomycetes, phosphate and potassium solubilizing microorganisms, nitrobacteria and denitrobacteria were detected after the wheat and maize straw chaffs were added to the tobacco cultivated soil. The effects of different straw chaffs on the microbial composition and quantity were analysed with biological statistic method. The results showed that the microbial quantity of the 20 40 cm soil layer could be significantly or highly significantly increased by adding wheat straw(7 500 kg/hm 2), maize straw(9 000 kg/hm 2 and 15 000 kg/hm 2)to the tobacco cultivated soil. |
